Design Science Releases MathPlayer 2.1

New version supports Internet Explorer 7 and adds
accessibility features

LONG BEACH, Calif. — September 17, 2007 — Design Science, Inc.
today announced the release of MathPlayer 2.1, adding support for Microsoft's
Internet Explorer 7 and new features to help students with vision and learning
disabilities. This new version reinforces the company's commitment to furthering
math-accessibility technology for web pages and braille.

MathPlayer's math-to-speech technology has been
enhanced to synchronously highlight the mathematics as it is spoken.
Synchronized highlighting can be a learning aid for all students, and has been
shown to be particularly effective for people with learning disabilities such as
dyslexia. MathPlayer 2.1 also supports DotsPlus, a braille math format for use with Tiger
braille printers, and seamlessly integrates with leading screen reader
software, such as JAWS, Window-Eyes, HAL, Read & Write, and BrowseAloud.

"MathPlayer 2.1 contains the initial results of our NSF
SBIR grant. There are many more exciting features coming in the next release,
both for people with vision impairments and for the general user. We are
committed to making MathPlayer the best viewer for math and MathML for
everyone." said Dr. Neil Soiffer, Senior Scientist at Design Science and the
grant's principal investigator.

"The continuing development of MathPlayer is an
outgrowth of Design Science's commitment to creating software tools needed by
the education, scientific and publishing communities to make math accessible. We
believe math can and should be made accessible, and we are working with the
accessibility community to make this goal a reality." said Steve Noble, Director
of Accessibility Policy for Design Science.

MathPlayer can be downloaded free from the MathPlayer area of the
Design Science website (www.dessci.com/mathplayer).
Anyone publishing web pages that include MathML can use the company's "Download
MathPlayer" button on their web pages, linking their readers to the free
software.
